/etc/fw_env.config not being created

if i have my uboot env defined in the script in ‎package/boot/uboot-tools/uboot-envtools/files/qualcommax_ipq807x`

is it ment to create /etc/fw_env.config?

as I have to manually create the above file to use fw_printenv or fw_setenv

Is this normal?

tplink,deco-x80-5g|)
	ubootenv_add_mtd "0:appsblenv" "0x0" "0x40000" "0x20000"

how come fw_printenv or fw_setenv dont look at the config in/etc/config/ubootenv as the details are populated there?

option dev '/dev/mtd9'
option offset '0x0'
option envsize '0x40000'
option secsize '0x20000'

Im having trouble with the device not switching root partitions during sysupgrade and i did not know if it is an envarg issue.

root@OpenWrt:~# fw_printenv bootargs
Warning: Bad CRC, using default environment
## Error: "bootargs" not defined
root@OpenWrt:~# 

there is a resemblence of correct args in appsblenv

Just looking at this for a different device and stumbled on your post.

yes

Shouldn't it be ubootenv_add_uci_config ? As in

ubootenv_add_uci_config "/dev/mtd9" "0x0" "0x40000" "0x20000"

Maybe?

EDIT:

As I keep learning about this...

File you maybe need to update is this: package/boot/uboot-envtools/files/qualcommax_ipq807x
uboot-tools/uboot-envtools doesn't exist in my tree.

It does not create a fw_env.config for me but I fixed my dual boot problem, I just need it to be accepted:
my device has the partitions split on different MTD's and the normal nand do upgrade does not work with that layout.

Great.
My problem is simpler but your post was very helpful in pointing me where I was messing up.

BTW... your PR is stuck for a fail in formalities. Having done a few PR myself, I suggest you redo the commit with a shorter title and no dot at the end, or probably it won't go any further.

Good luck!
